This invention relates to pumping appurw tus und more purtioularly wto uInetliodof 1nstallinff puinp'tubing into `ivell C21-sings. p

An `important object of the inventionfis 5 the provision ofa.,stlruoturek such that tlieuse of Well tubing extending entirely tothe top. of the Well :easing is eliminated und Au section. of Vtubingsubstituted therefor which 'gust sufficient to extend from the bottoniof' the Well to a point slightly above .the lower Iend of the Well Afurther object ot `the invention is to profvide a structure oftliischaracter permitting ready insertion and reilnovul of the tdbingSection. v
